What do you expect the tree to look like
I would expect it to be parsed correctly as val_definition
Where are you experiencing this error?

I'm unable to reproduce this on 696965e, parse result is
(compilation_unit [0, 0] - [4, 0]
(val_definition [0, 0] - [3, 1]
pattern: (identifier [0, 4] - [0, 5])
type: (function_type [0, 7] - [0, 23]
parameter_types: (parameter_types [0, 7] - [0, 13]
(type_identifier [0, 7] - [0, 13]))
return_type: (type_identifier [0, 17] - [0, 23]))
value: (block [0, 26] - [3, 1]
(lambda_expression [0, 28] - [3, 0]
parameters: (identifier [0, 28] - [0, 33])
(indented_block [1, 2] - [3, 0]
(val_definition [1, 2] - [1, 19]
pattern: (identifier [1, 6] - [1, 10])
value: (string [1, 13] - [1, 19]))
(identifier [2, 2] - [2, 6]))))))
Could you please check if erroneous behaviour remains?
Strange, I am no longer able to reproduce this issue on the original commit hash. Seems like this was an issue with some stale parts of treesitter on my machine. All good then and sorry for the trouble.
